Ultrasonic welding is an especially gentle joining technology for thermoplastic materials and nonferrous metals. Manual work stations are used in many ways in the plastics processing industry. The user manually loads the plastic components to be joined and removes them again from the machine after the weld process. The components can be welded with one or more ultrasonic sonotrodes depending on their size and geometry. Partially automated solutions support the work process for the production of high-quality thermoplastic products, but we also offer suitable platforms for copper and aluminum, i.e. for LI battery and cable harness applications. The development and production of all standard Herrmann ultrasonic machines, whether they are series or customized machines, takes place at the parent plant in Karlsbad, Germany.
Advantages of Herrmann ultrasonic welding machines
The HiQ product line, ULTRACELL, ULTRASAFE, punching and sealing machines or ULTRALINE are characterized by:
Weld process controllers guarantee high joining accuracy
Development and production 'Made in Germany'
Each machine is subjected to a strict functional and release check (FAT)
Realization of proven concepts with high technical standards
Wide-ranging applications in industry
Ultrasonic welding machines are mostly used in the industries AUTOMOTIVE, CONSUMER, ELECTRONICS or MEDICAL. Particularly where permanently strong, tight and visually impeccable connections are required. With all Herrmann Ultrasonic solutions, the fully digitalized ultrasonic generators guarantee reproducible results. The weld process is easy to optimize with specially developed controllers and suitable software.
The handheld ultrasonic welder HSG with ultrasonic generator in practical MobileCase is excellently suited to producing master samples or small series, or repairs. Standardized and individually designed sonotrodes for the HSG are available for different applications.
Basic principles for ultrasonics. The basics and more.
Ultrasonic welding of thermoplastic materials is a weld technology utilizing mechanical vibrations to generate heat due to molecular friction. These vibrations excite the molecules in the plastic so that they start moving. The plastic becomes soft and starts melting. The components are bonded by cohesive or form-fit joints After a short hold time under pressure, they are firmly joined molecularly.
